[564] The centre of the accompanying map of the world nearly corresponds with that of the Indo- 
Pacific Ocean, which is bounded on three sides by the great land-masses of the Old and New 
Worlds. Disjointed fragments of land separate the Indian from the Pacific division of the great 
ocean, and stretch like so many stepping-stones between the Malay peninsula and Australia, the 
latter semi-continental mass of land lying almost halfway between Africa and South America. 
The indigenous population of Australia presents one of the best marked of all the types, or 
principal forms, of mankind; and I shall describe the characters of this modification first, under 
the head of 

I. The Australioid Type (No. 5 tint on the Map). 

The males of this type are commonly of fair stature, with well-developed torso and arms, but 
relatively and absolutely slender legs. The colour of the skin is some shade of chocolate-brown; 
and the eyes are very dark brown, or black. The hair is usually raven-black, fine and silky in 
texture; and it is never woolly, but usually wavy and tolerably long. The beard is sometimes well 
developed, as is the hair upon the body and the eyebrows. The Australians are invariably 
dolichocephalic, the cranial index rarely exceeding 75 or 76, and often not amounting to more 
than 71 or 72. The brow- ridges are strong and prominent, though the frontal sinuses are in 
general very small or absent. The norma occipitalis is usually sharply pentagonal. The nose is 
broad rather than flat; the jaws are heavy, and the lips remarkably coarse and flexible. There is 
usually strongly

[565] marked alveolar prognathism. The teeth are large, and the fangs usually stronger and more 
distinctly marked than in other forms of mankind. The outlet of the male pelvis is remarkably 

These characters are common to all the inhabitants of Australia proper (excluding Tasmania); 
and the only notable differences I have observed are that, in some Australians, the calvaria is 
high and wall-sided, while in others it is remarkably depressed. No skulls are, in general, so 
easily recognizable as fair examples of those of the Australians, though those of their nearest 
neighbours, the inhabitants of the Negrito Islands, are frequently hardly distinguishable from 

The only people out of Australia who present the chief characteristics of the Australians in a 
well-marked form are the so-called hill-tribes who inhabit the interior of the Dekhan, in 
Hindostan. An ordinary Coolie, such as may be seen among the crew of any recently returned 
East-Indiaman, if he were stripped to the skin, would pass muster very well for an Australian, 
though he is ordinarily less coarse in skull and jaw. 

In the accompanying map, therefore, the deep blue colour (No. 5) is given not only to Australia, 
but to the interior of the Dekhan. A lighter tint of the same colour occupies the area inhabited by 
the ancient Egyptians and their modern descendants. For, although the Egyptian has been much 
modified by civilization and probably by admixture, he still retains the dark skin, the black, 

silky, wavy hair, the long skull, the fleshy lips, and broadish alas of the nose which we know 
distinguished his remote ancestors, and which cause both him and them to approach the 
Australian and the "Dasyu" more nearly than they do any other form of mankind. 

It is a most remarkable circumstance that no trace of the Australioid type has been found in any 
of the islands of the Malay archipelago, all the dark-skinned people who occur in some of these 
islands and in the Andamans being Negritos. On the other hand, no Negroid type is known to 
occur between the Andamans and East Africa, the darker elements of the Southern Arabian 
population being Australioid rather than Negroid. 

II. The Negroid Type (Nos. 1, 2, 3). 

As the chief representative of the Australioid type is the Australian of Australia, so is that of the 
Negroid type the Negro of South Africa (including Madagascar) between the Sahara and what 
may be roughly called the region of the Cape. 

[566] The stature of the Negro is, on the average, fair, and the body and limbs are well made. 
The skin varies in colour, through various shades of brown to what is commonly called black; 
and the eyes are brown or black. The hair is usually black, and always short and crisp or woolly; 
the beard and body-hair commonly scanty. Negroes are almost invariably dolichocephalic. I have 
not met with more than one or two skulls with an index of 80, while indexes of 73, or less, are 
not uncommon. The brow- ridges are rarely prominent, the forehead retaining a good deal of the 
feminine, or childlike, character. The norma occipitalis is often pentagonal, but not so strongly 
as in the Australioid skull. Prognathism is general; and the nasal bones are depressed: hence the 
nose is flat as well as broad. The lips are coarse and projecting. 

The Bushmen of the Cape area (No. 1) must be regarded as a special and peculiar modification 
of the Negroid type. They are remarkable for their low stature, the males rarely much exceeding 
four feet in height, while the females may fall considerably below that stature. Both sexes are 
remarkably well made. The skin is of a yellowish-brown colour, the eyes and hair black, and the 
latter woolly. They are all dolichocephalic; and the brim of the female pelvis has its antero- 
posterior diameter longer than the transverse, in a larger proportion of cases than in other forms 
of mankind. One of the most curious peculiarities of the people is the tendency to the 
accumulation of fat on the buttocks, and the wonderful development of the nymphas in the 
females. The Hottentots seem to be the result of crossing between the Bushmen and ordinary 

In the Andaman islands, in the Peninsula of Malacca, in the Philippines, in the islands which 
stretch from Wallace's line eastward and southward, nearly parallel with the east coast of 
Australia, to New Caledonia, and, finally, in Tasmania, men with dark skins and woolly hair 
occur who constitute a special modification of the Negroid type-the Negritos (No. 3). Only the 
Andamans have presented skulls approaching or exceeding an index of 80; all the other Negritos, 
the crania of which have been examined, are dolichocephalic. But the skulls of the eastern and 
southern Negritos present, as I have mentioned, a remarkable approximation to the Australioid 
type, and differ notably from the ordinary African Negroes in the great brow-ridges and the 
pentagonal Norma occipitalis . The best-known and the most typical of these eastern Negritos 

are the inhabitants of Tasmania and of New Caledonia, and those of the islands of Torres Straits 
and of New Guinea. In the outlying islands to the eastward, especially in the Feejees, the 
Negritos have certainly undergone [567] considerable intermixture with the Polynesians; and it 
seems probable that a similar crossing with Malays may have occurred in New Guinea. 

III. The Xanthochroic Type (No. 6). 

A third extremely well-defined type of mankind is exhibited by the greater part of the population 
of Central Europe. These are the Xanthochroi, or fair whites. They are of tall stature and have the 
skin almost colourless, and so delicate that the blood really shows through it. The eyes are blue 
or grey; the hair light, ranging from straw-colour to red or chestnut; the beard and body-hair 
abundant. The skull presents all varieties of forms, from extreme dolichocephaly to extreme 
brachycephaly. On the south and west this type comes into contact and mixes with the 
"Melanochroi," or "dark whites," while on the north and east it becomes mingled with the people 
of Mongoloid type, who bound it on that side. Its extreme north-west limit is Iceland; its south- 
west limit the Canary Islands; its south border lies in Africa north of the Sahara, in Syria, and 
Northern Arabia; its south-eastern limit is Hindostan; while in a northeasterly direction traces of 
it have been observed as far eastward as the Yenisei. I have not ventured, however, to draw the 
red bars which indicate the existence of this type, alongside of another, so far to the east, as one 
really knows very little about the people of Central Asia. 

IV. The Mongoloid Type (No. 8). 

An enormous area, which lies mainly to the east of a line drawn from Lapland to Siam, is 
peopled, for the most part, by men who are short and squat, with the skin of a yellow-brown 
colour; the eyes and hair black, and the latter straight, coarse, and scanty on the body and face, 
but long on the scalp. They are strongly brachycephalic, the skull being usually devoid of 
prominent brow-ridges, while the nose is flat and small, and the eyes are oblique. The Malays 
proper, and, I suspect, the indigenous people of the Philippines who are not Negritos, fall under 
the same general definition. 

On the other hand, the Chinese and Japanese, in whom the skin, hair, nose, and eyes are like 
those of the Mongoloids just mentioned, are dolichocephalic; and the Ainos, also 
dolichocephalic, are distinguished for the extraordinary development of hair on their faces and 

The Dyaks of the interior of Borneo are likewise dolichocephalic; and these people, and the 
Battaks of Sumatra, the so-called Alfurus [568] of Celebes, and the inhabitants of other 
easternmost islands of "Indonesia," seem to me to pass insensibly, through the people of the 
Pelew Islands, and of the Caroline and Ladrone archipelagos, into the Polynesians, in whom the 
straightness of the hair and the obliquity of the eyes disappear, while, in the majority, the skull is 
long and often approximates to the Australioid type. I have never met with a brachycephalic 
Maori, though I have examined a large number of New-Zealand skulls. Brachycephaly, however, 
occurs in the Sandwich Islands, and apparently in the Samoan Islands.- 

As linguistic evidence leaves no doubt that Polynesia has been peopled from the west, and 
therefore, possibly, from Indonesia, it becomes an interesting problem how far the Polynesians 
may be the product of a cross between the Dyak-Malay and the Negrito elements of the 
population of that region. I am inclined to think that the differences which have been over and 
over again noted between the elements of the population in Polynesia, and notably in New 
Zealand, may be due to such a mixed origin of the Polynesians. 

To the north-east, the Mongoloid population of Asia comes into contact with the Tchuktchi, who 
are said to be physically identical with the Esquimaux and Greenlanders of North America. 
These people combine, with the skin and hair of the Asiatic Mongoloids, extremely long skulls. 
The Mongoloid habit of skin and hair is also visible in the whole population of the two 
Americas; but they are predominantly dolichocephalic, the Patagonians and the ancient mound- 
builders alone presenting unmistakable brachycephaly. 

I have been much perplexed to know in what way to give a graphic representation of these facts. 
It seems quite impossible to draw any line of distinction, based on physical characters, among 
the so-called "American-Indians;" and therefore a uniform colour is given to the area which they 
occupy (8 c). I have given the Esquimaux area a different colour (9) rather for the purpose of 
reminding the student of the very peculiar character of the type, when well marked, than because 
I conceive it to be sharply distinguished from that of the North- American Indians. This colour (9) 
has by misadventure been extended over the Aleutian Islands and Kamschatka, which should 
rather in all probability receive the same hue as 8 B. The strongly coloured area (8 A), finally, is 
intended to indicate roughly the distribution of the Mongols proper. It is a most singular 
circumstance that there is the same sort of contrast, combined with certain definite points of 
resemblance, between a Mongol and an Iroquois that there is between a Malay and a New- 
Zealander; and [569] in the huge Americo-Asiatic area, as in the only less vast space occupied by 
the Polynesian islands, it is possible to find every gradation between the extreme terms. 

The four great groups of mankind, the areas of which have now been defined, occupy the whole 
world, with the exception of western and southern Europe, cis-Saharal Africa, Asia Minor, Syria, 
Arabia, Persia, and Hindostan. In these regions are found, more or less mixed with Xanthochroi 
and Mongoloids, and extending to a greater or less distance into the conterminous Xanthochroic, 
Mongoloid, Negroid, and Australioid areas, the men whom I have termed Melanchroi, or dark 
whites. Under its best form this type is exhibited by many Irishmen, Welshmen, and Bretons, by 
Spaniards, South Italians, Greeks, Armenians, Arabs, and high-caste Brahmins. A man of this 
group may, in point of physical beauty and intellectual energy, be the equal of the best of the 
Xanthochroi: but he presents a great contrast, in other respects, to the latter type; for the skin, 
though clear and transparent, is of a more or less brown hue, deepening to olive, the hair, fine 
and wavy, is black, and the eyes are of a like hue. The average stature, however, is ordinarily 
lower than in the Xanthochroic type, and the make of the frame is usually lighter. In Hindostan 
the Melanochroi pass by innumerable gradations into the Australioid type of the Dekhan, while 
in Europe they shade off by endless varieties of intermixture into the Xanthochroi. 

I have great doubts if the Melanochroi are to be regarded as a primitive modification of mankind 
in the sense in which that term applies to the Australioids, Negroids, Mongoloids, and 
Xanthochroi. On the contrary, I am much disposed to think that the Melanochroi are the result of 

an intermixture between the Xanthochroi and the Australioids. It is to the Xanthochroi and 
Melanochroi, taken together, that the absurd denomination of "Caucasian" is usually applied. 

Perhaps the most interesting fact which comes into prominence in the map of the distribution of 
these great groups of mankind, is the contrast between the broad and general uniformity which 
prevails over such an enormous area, exhibiting every diversity of climate and physical 
conditions, as that of the two Americas, and the singular variety crowded into a relatively small 
area elsewhere, as, for example, in the Pacific. Here, if we follow one and the same zone of 
latitude for a few thousand miles of longitude from east to west, we pass from Polynesian 
Mongoloids, in the Navigators, or the Friendly Islands, to Negritos in the New Hebrides, and to 
Australioids on the mainland of Australia. 

[570] A fact of this kind, taken alone, is sufficient to show that causes of quite a different 
character from mere changes of physical conditions, operating upon the same stock, must have 
been required to give rise to the phenomena presented by the present distribution of mankind.
